or AUBURN, NEW YORK, A CORPORATION'V DISK-HARROW TRUCK.

SPECIFICATION forming part of Letters IPatentlYifo. 760,708, dated May 24, 1904.

Application filedNOvember 30, 13908. Serial N0. 183,167. No model.)

To all whom 'it may concern,.-

Beit known that I, CHARLES S. SHARP, a citizen of the United States, residing at Auburn, inthe county of Cayuga-and'Stateof` New York, have invented certain new and useful Improvements in Disk-Harrow Trucks, of which the following is a full, clear, and eXact description. p

The object of my invention is to provide a truck for disk harrows that can be readily attached and detached.

Referring to the accompanying drawings, Figure l is a rear elevation of a disk harrow, showing the trucks in position. Fig. 2 is a side view of the same in section on line ma of Fig. 1. Fig. 3 is a perspective view of the frame of the truck. Figs. 4 and 5 are views 4 of the clamp.

A is the front frame-bar of the harrow, secured to the brackets B,in which are journaled the aXles u of the disks C, the spacingspools and square axle-bar being considered integral for the purpose of this description.

D is the frame of the truck; E, the wheel; F, a support on which the harrow rests when the truck is in use andto which the frame D is rigidly fastened. The front end of the frame D has a grip-piece b, and `between it and the support is the clamp H, through which the bars of the frame D pass. The clamp H is readily movable along the bars of the frame D, so as to permit of the attachment of the truck or of its detachment and also to accommodate harrows of diiferent widths of frame. The hooks c hold the clamp on the frame-bar and retain the truck in position.

In order to attach the truck, it is drawn beneath the harrow and between the disks untill the support ,F is directly beneath kthe axle of the harrow. The front of the truck-frame is then lifted,'bringing the support in contactn with the axle andl raising the harrow from the ground. When the truck-frame h as been raised to a suiiicient height, the clamp is moved up until the hooks o thereon are directly over the frame-bar A, when the frontend of the truck is lowered and thehooks c brought into engagement with the bar A, being held firmly in position by the weightjof the harrow.

` -When it is desired to detach lthe harrow, the front of the truck-frame is lifted and the clamp disengaged from the frame-bar A. The truckframe is then lowered until the harrow rests uponthe ground, when the truck can be pushed to the rear and from under the harrow or the latter can be drawn from over the truck.

I'do not limit myself to the precise construction of the clamp as shown, as it can be readily seen that the clamp can be shaped to grasp any. shape of bar used as the frame-bar of a disk harrow. v

Having thus fully described my invention,

what I claim as new, and desire to secure by l Letters Patent, is-

l. A removable truck for disk harrows or the like comprising a frame, a wheel atone end thereof, a slipport for the harrow', and a clamp movable on the frame tol adapt it to engage with the harrow-frame bar.

2. A removable truck for disk harrows or the like, comprising a frame having a wheel at one end, a support for the harrow, and an adjustable clamp carried by the frame to engage with the harrow-frame to hold the truck in position.

3. A removable truck for disk harrows or the like, comprising a frame having a wheel at one end, a support for theharrow, and a sliding clamp on the frame to engage with the frame ofthe harrow to hold the truck in position. A

A. A removable truck for disk harrowsor the like, comprising a frame, a wheel at one end, a support for the harrow on the frame, a grip to move the truck vinor out of position, and a clamp on the truck-frame to engage with the harrow-frame, the weight ofthe harrow holding the truck in position.

In testimony whereof I hereunto set my hand, this 19th day of November, 1903, in the presence of two attesting witnesses.
